If you can press your buttons fast enough it's a gain compared to both 5.2 with FnB macro and 5.2 w/o FnB macro. Previously you were completely at the mercy of your latency in how fast you could apply the FnB buff before casting a new spell.

The supposed QoL change doesn't remvoe latency from the equation, it just allows you to only apply F&B once instead of on each cast.
In 5.2, if you had the macro set up as such, you could just hold a modifier key (shift) and spam your Incinerate button to AoE. Letting go of the modifier would return you to single target. Using the same macro in 5.3, you have to release the modifier to continue AoE, then press it again to return to single target.

If you have a consistently bad connection, this change is good for you. Those of us with stable connections and a working macro are having to re-train our muscles to not screw up our AoE. There's also the accidental application of F&B below 1 ember, which does not automatically toggle off. Overall, bad change for many that we're having to adapt to.

Whole other subject though. This thread is for Doom. Thus far, there haven't been any conclusive changes, and the only mention of the spell has been a tooltip fix. Current logs show no difference.

Was the Chaos Bolt nerf an actual nerf or an odd tooltip change? Can someone do a number crunch to see if this doom nerf was just a tooltip from the 5.2 hotfixes or another further nerf?

I unfortunately quit some time ago but I am confused at these changes and concerned about the validity of forum echo.

afaik there has been no lock nerfs at all, it has just been tooltip updates for us, ofc we're talking about blizz here, they could have given us a stealth nerd but there is nothing to indicate nerfs in patchnotes or in game.

when dom ticks and you are out of meta, it does x dmg, however when you are in meta during a tick, it will get your meta mastery bonus and tick a lot harder. My dooms tick crit for 230k if I am in meta (the original dooms cast during the initial burst that is) and out of meta they only crit for about 110k. I wish there was an addon that showed when doom is about to tick so you could meta swap for max damage. Not sure if it would be worth the gcd though to be honest. Just maximise your meta uptime and you will see your big crits.

What? Doom doesn't work like that. It does the same damage in meta and caster form. Just go and test it on Dummy and you will see.

Yeah , dont mind my earlier post lol, I was looking at a different bit of dmg, misread an int buffed doom for a meta doom lol. And yeah brus, Ive been weaving since 5.0, I just realized how stupid my post was lol. Never actually paid attention to the reason behing the variable dmg in doom.
